Stuck in Android layout - Android Q&A, Help & Troubleshooting

Hi @all.
I currently try to design a "simple" layout with android. What it should do:
At the top and bottom of the screen should be a bar with a little content. LinearLayout, horizontal.
Between the bars is the space for the content.
This content should be devided into a "large" upper region and a linear layout with (right aligned) buttons at the bottom.
If there is not too much content the content area should be display centered in the available space. If there are more elements in the content, the area should grow until it fills the complete space between top and bottom bars. The Buttons below the content should always be visible. The area for the content should be scrollable in this case.
I tried something like this:
RelativeLayout
LinearLayout TopBar (AlignParentTop)
Button1 Button2 ...
LinearLayout BottomBar (AlignParentBottom)
ButtomA ButtonB ...
This works fine.
Then i tried to add an additional element
FrameLayout (Above Bottombar, Below TopBar)
This FrameLayout fills the remaining space. Fine.
Now i need a layout like this:
RelativeLayout (wrap_content Width/Height)
ScrollView
LinearLayout CONTENT (sometimes small, sometimes really large)
LinearLayout ButtonBar (horizontal)
ButtonX ButtonY ...
If i attach the buttonbar to the bottom of the relative layout the relative layout grows and does no longer wrap around the content. Instead it's height fills the complete available space.
If i put the buttonBar into the upper Relative layout i can fit it between Content and bottomBar. But if the contentn grows the buttonBar slides down outside the screen.
Is it possible that such a simple layout is not managable with Android?
I am working for hours on this and always something does not work :-( HELP PLEASE!!!
Best regards, Udo

I'm not sure how do that, but it's possible. Maybe using a table layout (a table row for each element) and assigning them different weights...

Hi there, I'm not sure if I get what you mean, but here is my understanding of the question.
When your content becomes too large, your bottom bar gets pushed out of the view ?
Try adding this line >> android:layout_weight="1"
into the parent view just above your layout button bar
example :
<LinearLayout ** add to this view here >
<ScrollView>
</ScrollView>
</LinearLayout>
<LinearLayout for ButtonBar>
</LinearLayout>
let me know if it works

I tried weight - does not work. Currently I use margins as described in various articles. Ugly, but it works.

Hi,
still stuck with this layout... Another problem now. I tried to have an inner LinearLayout set sets its children to equal width.
I tried every combination of weight, weightSum, layout_width="0sp" etc.
If the textView "MainContent" contains a huge amount of text the radio buttons are compressed to a very narrow size. If the text in the radiobuttons and the textview are nearly equal in size the layout works well. But ONLY then...
The scroll problem still exists.
The layout should work as follows:
If the screensize is big the MainContainer should use no more space than it needs to display its children. It the should be centered on the available space (in my real app it is packed into a relative layout instead of the top-level linear layout in this example).
If the content is larger than the available space a scroller should appear for the content in the scrollarea. The Buttons in the LinearLayout under the scrollview should still be displayed and not scrolled out of the screen. I currently am able to solve the scrolling problem by setting a bottom-margon of e.g. 50sp to the scrollview and -50sp to the linearLayout containing the buttons. Problem here: There are cases where the LinearLayout has no Buttons. With the current solution the Button-Area consumes space in this case too - what i do not want.
On both problems (Scrolling and even distribution of MainContent and the radioGroup) i now am working for days without success.
Any help would be nice. It looks like a really simple layout - but seems to be impossible with android.
Best regards, Udo

Maybe u want to use Fragments (use supportlibrary v4 to Support devices lower than honeycomb)
Use a big one for the Main content. And a small one for the button bar.
So the Fragment may handle the Main content, like an whole activity does.
But dont ask how, cause i have no idea how to do this.
Ok maybe its the solution, so good luck.

Hi,
i currently USE fragments ;-) This does not solve the layout problem...
At the moment i read into creating own custom layouts. Complicated but this seems to be the only way.
